BOX SCRAPER SETUP
READ AND UNDERSTAND ALL SAFETY STATEMENTS
Read all safety decals and safety statements in all manuals before beginning any Snow
Blower setup. Know and obey all OSHA regulations, local laws, and other professional
guidelines for your operation. Know and follow good work practices when assembling,
maintaining, repairing, mounting, removing, or operating this equipment.
EXCAVATING, GRADING, AND BACKFILLING
Park your prime mover on a level surface with this product properly attached.
Place your prime mover's transmission in "Park" and engage the parking brake.
Lower this product onto the level surface.
Make sure that the hydraulic cylinder is fully extended so that the ripper shanks are in the fully raised
position.
Shut off your prime mover's engine, remove the starter key, wait for all moving parts to come to a
stop, and relieve all pressure in the hydraulic lines.
Check to see that the cutting edges of this product are parallel to the level surface. If they are not
parallel, make the edges and the level surface parallel by following the instructions for adjustment of
the 3-point hitch as found in the operator's manual(s) for your prime mover and 3-point hitch.
Check to see that the bases of the main frame end plates are parallel to the level surface. If they are
not parallel, make the bases and the level surface parallel by adjusting the 3-point hitch's top link as
described in the operator's manual(s) for the prime mover and 3-point hitch.
SCARIFYING
Perform steps 1 through 6 above.
Check to see that the bases of the main frame end plates are leaning forward approximately 15
degrees relative to the level surface. If this is not the case, adjust the 3-point hitch's top link as
described in the operator's manual(s) for your prime mover and 3-point hitch. Leaning this product
forward 15 degrees will lift the cutting edges up a few inches off the level surface and will result
in the straight upper portion of the ripper shanks being perpendicular (90 degrees) to the ground
surface during operation.
Verify that the ripper shanks are set in the proper slot for performing the desired work. When the
front edges of the main frame end plates are flush with the ground level, then:
• positioning the ripper shanks in the lower slot will produce a 3-3/4" deep cut and
• positioning the ripper shanks in the upper slot will produce a 6-1/4" deep cut.
See RIPPER SHANK ADJUSTMENT AND REPLACEMENT in the Service section of this manual for
instructions on how to reposition the ripper shanks.
IMPORTANT
Operating this product with the ripper shanks only partially extended into the ground
CAN result in damage to this product and
WILL void all FFC warranties.
4. Restart your prime mover and raise the 3-point hitch. Completely retract the hydraulic cylinder to
extend the ripper shanks to their lowest and locked position. Failure to lower the ripper shanks
until the locking mechanism engages will result in excessive hydraulic cylinder strain and could
cause permanent hydraulic cylinder damage.
